Swash plate all over the place?

[Extensa]

Hi I have just finished going through the 3gx setup the swash moves fine in setup mode but as soon as setup completes the servos move all out of sink can anyone help? I have looked at the computer software but I don't know where to start with the settings on that :/

Hey.

Do you have the right eCCPM mixing type set within the transmitter?
Assuming this is on an Align machine you are going to need to set 3 servo 120 degree eCCPM, I have seen similar problems when this hasn't been set or it's be set to the wrong type.

What machine is this 3GX fitted to? Also what power supply/BEC are you using? If the BEC supply is not up to the job this can give similar results, in DIR all is ok, but once out of DIR mode and bound the channels do not move right.

If you can give me a little more information I will try and help as best I can.

Hi I'm using a Align TRex 600 nitro limited edition v2 with a Rce86t 2in1 regulator, Futaba r2008sb receiver and Futaba t8j transmitter I have the swash set to hn3 120 degree but there is two 120 degree swash settings might be on the wrong one

Hey.

I think you are using the wrong swashplate mixing, I think it needs to be HR3 off the top of my head. I'm not a Futaba user, but recently had someone come to see me with his models setup on the wrong mix.

I'll check and come back to confirm.

I hate to say it but it could also be your Align 2in1, while it's a great unit some have had problems with it not being powerful enough to run the servos when used in a flybarless setup. The 2.4ghz stuff hates to have the voltage drop below a certain point, if it does funny things happen and what you are describing I have seen happen both on the forums and on my own model with an underrated BEC on an electric model. It was all ok in DIR mode, but out of it and ready to fly the servos just jittered all over the place.
Have you seen any flashing lights on your Futabe receiver? A sure sign of a power problem, well it is with Spektrum gear.

Cool thanks for that fingers crossed it will work

Back again. Yep, you're using the wrong swashplate mix. Needs to be HR3, some good diagrams here;

Futaba® Radio System Frequently Asked Questions (FAQ)

That is why the 3GX is going belly up when the gyros are working, as they are controlling the wrong servos.

Probably not the 2in1 now luckily, but keep this unit in mind for future upgrades as your skill level improves and you place more loads on the servos.

You're very welcome buddy, glad to help. Any other questions or if you get stuck give me a shout.

I also have some 3GX settings files you can open up in the PC software and then write across to your 3GX to make it fly much better than the stock, out the box settings. I have posted them in this forum, but if you get stuck finding them let me know and I will email you them.
They have been used and approved by many forums users now, so you will have less to worry about.

Hey.

Yeah I'll be glad to help with these questions. I've just come off the pc and tapping this out on my phone, so if its ok I'll email you tomorrow with my answers to your questions, the settings and some pitch & throttle curves to use as a starting point.
It'll be easier than me trying to answer on a tiny keyboard.

Back in the morning.
